Description

When multiple configuration files are used and default merge strategy is in place, the attribute "packages" of the latest configuration takes precedence. However multiple configuration files may declare custom Appenders defined as @Plugin and these plugins may be declared in different packages.

The proposed improvement is to perform merging of "packages" attributes from multiple configuration files in DefaultMergeStrategy.
